Question An object is located in air 25 cm from the vertex of a concave surface made of glass with a radius of curvature 13 cm. Where does the image by refraction form? Use n'air = 1 and glass = 1.6. (Give the image distance in centimeters with the appropriate sign.) HINTS: For the sign on the focal length, the glass is concave. For the sign on R, the object is in the air side, not the glass side. ст What is its magnification? m = +

The fission of 1 kg of uranium produces 8.0 × 1013 J of energy. (a) Calculate the mass, in grams, converted to energy by the fission of 0.85 kg of uranium. (b) What is the ratio of the converted mass to the original mass? 

2. Calculate the open circuit voltage at 800 °C for a Solid Oxide Fuel Cell that is fed with pure hydrogen on anode and pure oxygen on cathode. JUST SOLVE 2nd QUESTION PLEASE :) 1. For a Solid Oxide Fuel Cell that uses hydrogen as fuel, what is the maximum energy output possible at 800°C. 2. Calculate the open circuit voltage at 800 °C for a Solid Oxide Fuel Cell that is fed with pure hydrogen on anode and pure oxygen on cathode.

Many companies are undergoing server virtualization. This is the concept of putting multiple "virtual" servers onto one physical device. The payoffs can be significant: fewer servers, less electricity, less generated heat, less air conditioning, less infrastructure and administration costs, increased flexibility, less physical presence (that is, smaller server rooms), faster maintenance of servers, and more.

Consider the power system, shown in the figure below. Consider Bus 1 to be the slack bus, Bus 3 is the PV bus, maintaining its voltage magnitude at 1.02pu. 1) Obtain the power flow solution for the system. Show your steps. 2) Using the Inverse Jacobian matrix, AND WITHOUT SOLVING THE POWER FLOW PROBLEM AGAIN, how would adding 1pu (Q) support on Bus 2, affect voltage magnitude on Bus 2?
